Load Balancing Concepts
Last updated: 3/2/2026Goal
The goal of this page is to understand what the term Load Balancing
can be in the context of a Qlik site.
Load Balancing
When it comes to load balancing within the scope of Qlik, there are three general areas that are applicable:
- Load balancing across Qlik proxies
- Third-party network load balancer required
- E.g. F5 BigIP, NGINX, Netscaler, AWS ALB, Azure Application Gateway, etc
- Requires support for websockets and sticky sessions
- Required for Qlik Proxy resilience
- Load balancing across Qlik Engines
- Native to Qlik at the proxy level
- Pure round robin
- Option to plug in custom load balancer
- Load balancing rules for applications
- Native capability allows for
pinning
of applications to specific engines
For documentation/examples around load balancing rules, please refer to Creating load balancing rules with custom properties.
